This account was originally began as a parody of the "Grand Solar Minimum" movement, an attempt to hook a few in (quite successful, I might add!) thinking GSM is in total control of climate when the reality is, there's no GSM.
An explainer
1/
Sunspots are magnetically active areas on the "surface" and a few hundred Km below on the sun. Remember that the sun is this 1.4 million Km diameter ball of superheated gas (~25% Hydrogen, 23% Helium, & some heavier elements) and the surface is constantly changing.
2/
Sunspot cycles are roughly 11 years long, can be over 14 or as short as 7, there's actually a 2-part cycles with northern and southern hemisphere components. There's a small change in solar energy activity compared to sunspots, here's a time comparison of the two: 3/
Breaking this down into "Spots Vs Watts" there's a lot more noise going on, there have been some very high insolation months with no measurable sunspots. Overall there's a correlation but it's not "bulletproof" at r² 0.56. 4/
One reason is even though spots are generally between 30°S - 30°N on the sun, the earth only receives a tiny portion of the sun's light, and almost all of it is equatorial. How much sunlight do we receive???
Roughly 1 part in 1.15 billion of the sun's total output.
5/
These is a revised chart for solar output including the last year. We're on the upswing for cycle 25, we're now just slightly above the average for the last 313 years of observational and proxy data.
So relax, there's no solar minimum...
And even if there were one... 6/
We see that the sun over the last 8770 years has had very little variability, less than 1 part in a thousand from maximum to minimum (decadal time frames) and the periods of greatest solar activity were not the hottest, nor weakest activity the coldest.
Thanks for your time! 7/8
This was not intended to be released sequentially but I hit the wrong icon by mistake- happens from time to time.
There's a lot of information here, but as usual I'm here for questions if you have any.

There's a lot of misunderstanding on electrical power generation, it's part of the reason why many think wind power is more expensive or requires more infrastructure, even though the oposite is true. So let's get electricity generation!
1/17
Take a coil of wire- spin a magnet inside of it, and you generate electricity.
Thank you folks, you've been a blast, good night!

Okay, so it's a bit more complicated than that (and more about that way later), we need to spin that magnet.
There's a lot of ways to spin that magnet, and most of those involve generating high pressure steam. (I'll do hydropower later)
